"I have created extra code in 'init' that loops waiting for the partitions to become available. 

Now, at bootup, when you see this message: 

Loading drivers needed to access disk drives... 

You will see dots appearing on the end each second, about 5 seconds for the first loop, then a couple more seconds for the second loop. The second loop displays **red dots**, so you can see how long the wait has had to go into over-time. 

If you don't have any USB storage devices plugged in, you only get a 3 second delay total. 

The end of the story is I was able to save a session to the USB drive and it was recognised and usable at next boot. Yippeee!"
